Which Language should I Choose for a Local host Accounts Software?

  asp.net, c#, jsp, php, python

My company wants a Accounts Software to Office in own (For some Personal options in Accounts Software which are not available in many Accounts Software). So, We started in creating the Accounts Software but they said it should run as a local host on our server and not as a installed software on pc. So, we need a dynamic Programming Language to build! Which Dynamic Programming Language is best to build a Local Host Web Application?
